Flotation Reagents Mineral Processing & Metallurgy

Flotation Frothers What is the Function of Frothers. The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the non-floatable minerals. Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form.

That is the successive removal of two or more valuable minerals from each other by flotation. For example, the separation of each copper, lead, zinc and iron sulphides from a single ore is selective flotation whereas the flotation of the combined sulphides from the gangue is referred to as bulk flotation. 18.3.

Sodium Silicate in Phosphate Flotation

Some factors adversely affect the efficiency of anionic flotation of phosphate in the absence of sodium silicate, thereby decreasing the concentrate grade. Impurities originally present on the quartz surface might be responsible for this adverse effect, but the precipitates heterocoagulated onto the surface of quartz also appeared to play a role.

Bench Scale Flotation of Spodumene/Quartz and Lepidolite

Based on results of zeta potential determinations and microflotation tests, bench scale flotation experiments were carried out using spodumene/quartz and lepidolite/quartz synthetic mixtures. Pure natural samples, further purified in laboratory, and commercial reagents were employed. The minerals were characterized by X-ray diffraction technique.
